Filed: 1962-12-07
Abstract: 989,754. Manufacturing stranded conductors. BRITISH INSULATED CALLENDERS CABLES Ltd. Dec. 6, 1963 [Dec. 7, 1962], No. 46272/62. Heading H1A. In a stranding machine for making transposed multiple strip conductor of substantially rectangular cross-section wherein component strips 23 are drawn from bobbins 11 mounted on cradles 2, disposed around the machine axis and about which they orbit with a planetary motion, there is provided for each strip a guiding die 12 with a throat of rectangular cross - section, its length being several times the width of the strip. Means are provided for rotating the dies (with the bobbin holders) about axes perpendicular to their cross-sections and passing through the centres of symmetry thereof or about axes substantially parallel thereto at the same angular speed as, but in the opposite direction to the plate carrying the cradles and bobbins, so as to maintain the major transverse axis of each die aperture substantially parallel with the major axis of the cross-section of the strip as it passes through the positioning head or transposing device. Figs. 1 and 3 show a back plate type of planetary device wherein the strip-guiding dies 12 are mounted upon forwardly-extending arms 9, 10 fixed to the bobbin cradles 2. The die aperture is formed by inwardly facing curved surfaces and its length is such as to prevent the edge of the strip from making contact with the bobbin flanges whilst being unwound. Back rotation of the bobbin cradles is obtained from cranks 13 (Fig. 2, not shown) fitted on the rear ends of shafts 3 and coupled to ring 14 either directly or by links 15. The invention may be used with a bobbin-carrying device of the cage type in which each bobbin cradle is supported at both ends, by front and rear trunnions turning in front and rear rotary discs. In this case, the front trunnions must be large enough either to accommodate the guiding dies or to allow for the side to side movement of the strips in such dies mounted forwardly of them.

Title: Activated sludge process for waste water purification
IPC: C02F1/38
Filed: 1977-11-14
Abstract: In biological effluent treatment by the activated sludge process, the concentration of the degradable impurities in the effluent fed is maintained so high that the formation of bulking sludge is promoted. This is effected by adjusting the space loading to a value from 1 to 2. Due to the degradation properties of the microorganisms forming the bulking sludge, more organic pollution load in the effluent can be degraded. Subsequently, the activated sludge is separated from the treated effluent and at least partially recirculated.

Title: Bowling ball return apparatus
IPC: A63D5/02
Filed: 1972-10-19
Abstract: 1396542 Bowling ball return apparatus AMF INC 17 Oct 1973 [19 Oct 1972] 48160/72 Heading A6D A ball exit arrangement for a bowling ball return apparatus comprises a ball receiving device 15 movable from a ball retaining position (Fig. 1) to a ball discharging position (Fig. 8) upon the receipt of a ball, such device being adapted for positioning between the pit ends of adjacent bowling lanes, and means 14 for sweeping the vicinity of said ball receiving means whereby a bowling pin inadvertently received therein is ejected therefrom. As shown the device 15 comprises a pivotally mounted trough held in its retaining position by an arm 26. When a ball enters the trough through an exit 16 from either of adjacent pit ends it contacts a micro switch 18 which operates a solenoid device to release arm 16 so that the trough moves to its discharge position, under the weight of the ball and against the tension of spring 29, to discharge the ball on to rails 31 so that it comes into contact with a ball return belt 33 and is thereby returned to the bowler. The trough is continuously swept by a reciprocating paddle 14 so that if a bowling pin inadvertently gets into the trough it is ejected by the paddle 14. With a pin the discharge mechanism is not operated even if the switch 18 is contacted because the force in spring 29 is such that whereas the weight of a ball is sufficient to overcome it the weight of a pin is not. The spring 29 also acts to return the trough 15 to its retaining position after a ball has been discharged therefrom and the arm 26 automatically locks the trough in its retaining position. The ball receiving device also incorporates a pivoted gate 17 which overlaps with the trough 15 when the latter is in its retaining position and ensures that no bowling pin can enter between a ball and the trough and gate to cause jamming of the mechanism. The ball receiving device may alternatively be in the form of a hollow cylinder rotatable about its axis and having a hole through which a ball can be discharged.

The quasi-random code is generated in a unit comprising a clock generator 12 which drives a shift register 10 via a feed-back circuit 11. The code and the signal from an HF oscillator 2, frequency modulated by a sawtooth voltage from an oscillator 1, are fed into a phase modulator 3. After passage through an amplifier 4, the output signal from the phase modulator 3 is transmitted via and is reflected back to an antenna 5 and the transmitted and the reflected signals are mixed in a mixer 6 from which the differential signal is supplied to an amplifier 7 with a narrow pass band. If the differential signal has a frequency within the pass band and has an amplitude which exceeds a certain threshold valve, the signal is detected in a circuit 8 and conveyed to a decision circuit 9 for firing the proximity fuze.

Fig. 2 shows the outputs obtained from the X (26) and Y (28) sense windings when, following an input reset, pulse inputs are applied through set winding 22, inhibit winding 24 or both together, the flux patterns produced in the plate 1 in each case being described (Fig. 3, not shown). The X winding will provide an " Exclusive Or " function since it will provide an output if there is a signal in either winding 21 or winding 24, the polarity of the output indicating from which winding the signal was applied. The Y winding can be used to provide a clock pulse and may be arranged to link certain other legs to achieve a similar output. A logical AND gate is described (Fig. 4, not shown) incorporating three magnetic plates having their set and re-set windings connected in series and independent inhibit windings, their X output windings being connected together and in series with a single Y output winding provided on one plate only to form the gate output. A transistor 40 having its base connected to the output winding circuit is made conductive on occurrence of a reset pulse only if this has been preceded by application of inhibit pulses to the three inhibit windings simultaneously with a set pulse. In another gated AND circuit incorporating three transistors (Fig. 5, not shown), Y output windings are provided on the first two plates only and link a magnetic leg 13. If more than one inhibit pulse is supplied as an input to a plate the device can act as an OR gate.
